SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 754,120, dated March 8,1904.

Application filed August 25, 1902. Serial No. 121,008. (No model.) i

bed-bottoms; and its object is to provide a means whereby thelongitudinal tie-rod may be manipulated to expand or contract thebedbottom laterally. I attain this object by the mechanism illustratedin the accompanying drawings, in which- Figure l is a top plan of aspring bed-bottom, showing the manner of attaching the longitudinaltie-rods. Fig. 2 is the same, showing a modilied form of longitudinaltie-rod;

and Fig. 3 is an elevation of the longitudinal tie-rod, showingindentations for the reception of the lateral tie-rods.

Similar letters refer to similar parts through'- out the several views.

In the accompanying drawings, A represents ordinary spiral wire springsin common use in spring bed-bottoms, and C represents the ordinarylateral tie-rods. My invention consists in the peculiar manner ofconstructing and applying the longitudinal tie-rods, which consists inbending the rods to form alternate parallel portions B of proper lengthto engage alternate pairs of springs, as shown in Fig. 1, and oiIsetsB', formed in such a manner that these angled osets may be adjusted, asindicated by the dotted lines in Figs.

l and 2, to make the bed-bottom wider or narinstead of each parallelportion connecting two springs in each alternate row the parallelportions alternate regularly with each alternate spring in adjacent rowsand the offsets extending back to unite parallel or adjacent springs.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

In combination with a spiral-spring bed-bottom, longitudinal tie-rods,osets to engage alternate springs in adjacent parallel rows, saidlongitudinal tie-rods supported above the upper coils of the springs andprovided with depressions to engage and interweave with the lateraltie-rods below the upper coils of the springs, substantially as and forthe purpose set forth.
